🔋 Battery

A battery is a device that stores chemical energy and changes it into electrical energy. Inside the battery, chemicals react and push tiny particles called electrons to move. The movement of electrons creates electric current that can power devices.

Examples:

• 🔦 Flashlights use batteries to produce light.

• ⌚ Watches use batteries to keep running.

• 🎮 Remote controls use batteries to send signals.

• 🚗 Electric vehicles use batteries to run their motors.
